Imperas RISC-V Solutions

Imperas RISC-V Simulators

The Imperas ISS (Instruction Set Simulators), System Emulators, and Virtual Platforms have been developed and commercially supported for over 10 years. They are based on the Open Virtual Platforms (OVP) models and technology where there are currently over 200 processor model variants and over 250 platforms and peripheral models available.

The simulators are released to run in x86 Windows/Linux host PC environments.

Imperas Debuggers

Imperas simulators provide a gdbServer port enabling the connecting of RISC-V GBD debuggers to the simulator to allow the debugging of software running on bare metal platforms. This works well for a single processor design and Imperas comes with appropriate GDBs for the different cores and also provides the scripts and launch technology to allow very easy use of Imperas RISC-V simulators with GDB/Eclipse for IDE and single core debug.

If you are doing multi-processor design then a single GDB will not give you the debug experience that your project timescales will require... In that instance you should look at the Imperas Multi Processor Debugger - which allows the debugging of SMP and AMP, homeogeneous, and heterogeneous multi-core designs. The Imperas Multi Processor Debugger also enables co-debug of the source of the platform behavioral components.

Imperas models of standard RISC-V cores and platforms

Imperas and its partners develop many models of processors, cores and platforms. Several of these components can be used as is, and can added to your own platforms. Most of these models/platforms come as open source under an Apache 2.0 license and can be easily modified. If you need models of standard platforms, that you can use or extend - then you require Extendable Platform Kits (EPKs).

Many EPKs come out-of-the-box running with standard operating systems such as Linux or FreeRTOS.

Videos showing RISC-V simulation and debug

There are several video on the use of RISC-V ISA and core models with the Imperas simulation and debug solutions.
Please have a look at: http://www.imperas.com/imperas-videos where you will find videos showing very fast simulation on bare metal, operating systems running like FreeRTOS, and multi-core debug across RISC-V based platforms.

We then modeled the HiFive Unleashed development board from SiFive. This includes the U54-MC 5 core 64bit RISC-V processor that can run SMP Linux. To see this virtual platform booting SMP Linux and being debugged with the Imperas Multi-Core Debugger look at the video here.

Imperas solutions for early software development have never been more appropriate with development schedules more critical than ever. We believe that simulation-based verification is fast becoming an essential requirement in complex SoCs, and together with advanced debug and analysis tools for many-core and heterogeneous designs will greatly reduce development schedules for next generation devices.
